The capability integrates two key systems: OSRL’s Split Lowering System (SLS) developed with InterMoor, and the new Snub Line Winch System, developed by Oceaneering. Together, these technologies enable capping stack deployment when surface conditions make conventional vertical access unsafe or impracticable. The SLS allows the stack to be deployed, positioned, and lowered from an offset location outside the hazardous surface plume, while the Snub Line Winch System provides controlled final alignment and landing on the BOP or wellhead.
Vania De Stefani, Chief Executive Officer at OSRL, said: “This shallow-water deployment capability reflects OSRL’s continued investment in strengthening industry readiness for complex subsea incidents. By bringing together the Split Lowering System and Snub Line Winch System, it helps support safer, controlled capping stack deployment in challenging shallow-water scenarios and reinforces the value of collaborative preparedness across the industry.”
Key benefits include:
- Enables deployment where surface conditions prevent safe vertical access
- Provides improved control during the final landing sequence
- Supports deployment in water depths from 75 to 600 meters
- Enables rapid mobilization from OSRL’s Norway base by sea or air
- Supports installation without a seabed interface of components
The launch enhances OSRL’s shallow-water capping capability, supporting members in complex well-control scenarios and reinforcing industry readiness for low-frequency, high-consequence subsea incidents.
